I'm trying to get a clean list, but since some games get filtered, some useful clones and bootlegs, or english bootlegs of japanese games, i use the "don't filter these roms" in the gameex configuration. There are 20 games in my list, 3 of them are still filtered and i can't find why. Questions : - Do i need to put the file extension in the list (like ssft2.zip) - The games that are still filtered are : wbmlbg.zip; wbml.zip; ssrderuac.zip I've upgraded to the last version of gameex and mame, the same games are still filtered. I've checked them directly on mame and they work fine so i don't understand why they get rejected by the gameex filter. One option i thought of would be to take a whole unfiltered list and put the games i want to block in the "always filter these games", my question about that is what is the field length of that ? Thank you all for your answers, it is very unfortunate because these few games that are filtered are the ones i really want to play (sucks huh ?)
